I have a 91 CRX with a 94 Ex Vtec motor. My temp gauge rarely ever rises even after I have been driving for a couple of hours. But when I sit in traffic for a little while then my temp gauge rises to where it should be then when I start moving again the gauge goes all the way back down. Then sometimes while I am driving the needle just all the sudden begins rising to the top and I have to pull over and let it cool down then its normal again. The other problem that I have is that no coolant ever goes into my overflow tank. Does anyone know that problem. Thanks.

You probably have a sticking thermostat. When the unit begins to fail, the valve gets a little sideways and gets hung up on the center shaft. The shaft will have new, clean striations.

Yeah, i'd say replcae the thermo and put some fresh HONDA coolant in there while you're at it. :wink:
